摘要

A toner powder for the development of latent electrostatic or magnetic images, the toner powder containing a polyester resin based on an etherified diphenol and a dicarboxylic acid mixed with a reaction product of an epoxy resin and a phenol compound or a carboxylic acid, and the process for forming fixed images on an image receiving material utilizing the above toner powder, the surface of an intermediate medium consisting of material having a lower affinity for the softened toner powder than does the image receiving material and the toner powder being softened by heating before and/or during transit through a pressure zone.
